T1167GT2 - CK Worldwide 2% Thoriated Tungsten Electrodes (Red) - 1/16" x 7" (10-Pack)

Premium 2% Thoriated Tungsten for Professional DC TIG Welding

The CK Worldwide T1167GT2 is a pack of ten 2% Thoriated tungsten electrodes, widely recognized in the industry by their red color code. Measuring 1/16" in diameter and 7" in length, these electrodes are manufactured to meet AWS A5.12 specifications for classification EWTh-2 (or WT20). Thoriated tungsten has long been the standard for Direct Current (DC) welding applications due to its exceptional operating characteristics.

The addition of 1.7% to 2.2% thorium oxide to the tungsten base significantly improves the electrode's electron emission qualities. This results in easier arc starting, a more stable arc, and the ability to carry higher currents without the tip melting back or spitting. For professional fabricators working with carbon steel, stainless steel, nickel alloys, titanium, or copper, this electrode provides the consistency required for X-ray quality welds. The medium erosion rate means you spend less time regrinding your tip and more time welding.

While thoriated tungsten is slightly radioactive, it remains a top choice for industrial applications where arc stability is paramount. It is specifically designed for DC Electrode Negative (straight polarity) welding. Although it can be used for AC welding on aluminum in rare specific setups with a modified point, it is primarily optimized for DC. These electrodes feature a ground finish, ensuring precise diameter control for consistent collet fitment and electrical conductivity.

Key Technical Benefits

Choosing CK Worldwide ensures you are getting high-quality tungsten that is free from internal defects that can cause wandering arcs. The 2% thoriated composition offers a higher melting point than pure tungsten, allowing for a sharper point retention during welding. This is critical for root passes on pipe or precision work on thin-gauge stainless steel where heat control is essential.
